Agastache plant named ‘Peachie Keen’

ABSTRACT

A new and unique cultivar of  Agastache  plant, named ‘Peachie Keen’ with large peachy colored flowers in tightly clustered verticils. The plant habit is compact and upright with a long bloom time and usefulness in the landscape extended by the persistent and colorful mauve calyxes.

Botanical denomination: Agastache spp.

Variety designation: ‘Peachie Keen’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct plant cultivar ofHyssop or Anise Hyssop from the genus Agastache and given the cultivarname ‘Peachie Keen’ previously known internally by the breeder codeHK-10-18-02. The new plant was the result of a planned cross in thesummer of 2010 by Kevin A. Hurd and Hans A. Hansen between Agastache‘Firebird’ (not patented) as the female or seed parent and Agastache‘Ava’ (not patented) in a mixed isolation bed as the male or pollenparent. The seed was collected in September of 2010 and the new hybridwas first isolated from trials at a nursery in Zeeland, Mich. during thesummer of 2011 and selected for final introduction in the summer of2012. Agastache ‘Peachie Keen’ has been asexually propagated at the samenursery in Zeeland, Mich. using traditional shoot tip and stem cuttingprocedures and found to reproduce plants that are identical and exhibitall the characteristics of the original plant in successive generationsof asexual propagation.

The new plant, Agastache ‘Peachie Keen’, has not been observed under allpossible environments. The phenotype may vary slightly with differentenvironmental conditions, such as temperature, light, fertility,moisture and maturity levels, but without any change in the genotype.

In comparison to the seed parent, Agastache ‘Firebird’, the new cultivar‘Peachie Keen’ has peachy-colored flower petals rather than the reddishorange flower petals of ‘Firebird’, and the flower buds on ‘PeachieKeen’ are more orange and less red than the buds of ‘Firebird’. Incomparison to the male plant in the isolation bed, Agastache ‘Ava’, thenew plant has flowers with much less red petals and calyxes with lessintense red with a green undertone.

The new plant Agastache ‘Peachie Keen’ is distinct from the parents andall other Hyssop known to the inventors in the following combinedtraits:

-   -   1. Compact upright well-branched habit;    -   2. Large peachy-colored flowers in tightly clustered verticils;    -   3. Long bloom time with effectiveness extended by persistent        mauve-colored calyxes.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance ofthe plant, including the unique traits. The colors are as accurate asreasonably possible with color reproductions. Ambient light spectrum,source and direction may cause the appearance of minor variation incolor.
